| − | '''Hydronium''' is a common [[Polyatomic Ion]]. Its [[chemical formula]] is <math>H_3O^+</math>. | + | '''Hydronium''' is a [[Polyatomic Ion|polyatomic ion]]. Its [[chemical formula]] is H<sub>3</sub>O<sup>+</sup>. It is often simplified to H<sup>+</sup> in writing chemical reactions. |
| − | Hydronium is present in all aqueous [[solution]]s, as the [[acid]]ic counterpart to the [[alkaline]] [[hydroxide]] (<math>OH^-</math>). A hydronium ion will combine with a hydroxide ion to create two [[water]] (<math>H_2O</math>) [[molecule]]s. An imbalance will shift the [[pH]] down if hydronium is more dominant. | + | Hydronium is present in all aqueous [[solution]]s, as the [[acid]]ic counterpart to the [[alkaline]] [[hydroxide]] (OH<sup>-</sup>).
